12. Librarian

Librarians have a lower-than-average hiring outlook but they rank so high in other criteria, such as low stress level and better office environment than average, that they squeaked into the top 12 list of most underrated jobs.

"Librarians have an opportunity to work in an environment they love. They have good hours. And they're serving the public, which is what most librarians get into this business to do," Lee said.
